Photoshop: MS Word 7 unsucessfuly tries to open Photoshop documents

When I click on a saved photoshop image, Microsoft Word has started (unsuscessfuly) to try to open the image. If I open photoshop first, then I can open the image from photoshop and everything is OK.
Dose anyone have any ideas?

Windows XP is the file format and Word tries to open all jpeg's.
I just had one of those duh!!! moments and I changed the "opens with" tab in properties. Photo's etc are now opening in photoshop.
Some days I"m worse than others. :)
Thanks,
Gar
